Total and dissociative photoionization cross sections of N2 from threshold to 107 eV

Abstract

The absolute cross sections for the production of N+ and N+2 have been measured from the dissociative ionization threshold to 115 Å. In addition, the absolute photoabsorption and photoionization cross sections are tabulated between 114 and 796 Å. The ionization efficiencies are also given at several discrete wavelengths between 660 and 790 Å. The production of N+ fragment ions are discussed in terms of the doubly excited N+2 states with binding energies in the range 24 to 44 eV.
